UCC3808APWTR-2 Application Field and Working Principle

PMIC - Voltage Regulators - DC DC Switching Controllers

The UCC3808APWTR-2 is an integrated circuit designed for synchronous buck switching configurations and for DC-DC converters. It is designed to provide a high-efficiency, high-current, high-power design solution for off-line power supplies and on-board DC-DC applications, such as low-power to high-power electronic system power solutions. This device integrates a MOSFET gate driver, and a linear regulator to provide a complete synchronous buck solution, and features a high-efficiency and high- power operation that is ideal for a wide range of applications.

The UCC3808APWTR-2 is specifically designed to work with non-isolated, synchronous buck converters, providing constant-current and constant-voltage output. This device can be used to drive a single MOSFET operating in a full-bridge configuration, which allows for fast switching times, high-power efficiency and high-capacity loads, making it suitable for applications such as small-form factor, low-power-consumption systems.

When using the UCC3808APWTR-2, the power supply must be connected to the device’s main power supply input. This power supply must meet the operating requirements of the device, and must provide the desired output voltage and current. The upper and lower gate count allow the output to be regulated, and the output power can be adjusted using the on-chip linear regulator. The UCC3808APWTR-2 also features a slew-rate function, which prevents output power spikes during hard switching, allowing for more stable output characteristics.

The UCC3808APWTR-2 can also be used to provide an adjustable voltage, allowing for applications such as portable electronic equipment, as well as industrial equipment. It features an adjustable soft-start, which helps prevent large inrush currents, leading to optimized system operation. The device also features a wide supply voltage range, allowing it to function with a variety of power supply configurations.

The UCC3808APWTR-2 is an ideal choice for applications that need high-power, high-efficiency synchronous switching for off-line and on-board DC-DC applications. Its simple design, low-cost, and ease of use make it an attractive solution for a wide range of applications.
